Specification of Letters Patent.

Application ined March 5, 192i. seriai No. 449,705. L y

To all whom t may con-nervt:

"Be it known that 1, FRnnERici; F. SCHMITT,

'a citizen of the lnited States. residing at' One object of my presentinvention is lto provide an improved mattress lwith a novel form ofbacking sheet for the top and bottom and which can/be used with'advantage in a Vmattress embodying the principles of construction ascovered in my United States Patent, No. 1,014,261; my improved backingsheets serving as means for retaining in shape the sides and ends of themattress case and the plaited and tufted portions of the top and bottomduring the time when the mattress is being made and when it is beingused.

vAnother object'of my invention is to make my improved mattress of'adurable and coniparatively simple constructionand so that it can bereadily manufactured.

These objects, and other advantageous ends which will be describedhereinafter` 1 attain in the following lmanner, "reference being had tothe accompanyingdrawings in which- Figure 1 is atop plan view of amattress including my present invention, y

Figure 2 is an enlarged section taken on tlie line 2-2 of Figure 1;y aportion of the length being broken away; the filling being` omitted inone part,

Figure 3 is an enlarged section taken on the line 3-3 of Figure 1; aportion of the length being broken away,

Figure 4 is a perspective view illustrating` my improved backing sheetpositioned relatively to the top or bottom of the .mattress` Figure 5 isa perspective view of one of my improved backing sheets,

Figure 6 is a fragmentary enlarged plan view as it appears when lookingfrom the inside of the mattress with the filling omitted,

Figure 7 is a view of similar character to Figure 6 looking from theoutside of the mattress before the tufting takes place,

Figure 8 is a fragmentary enlarged section showing more clearly thearrangement of the plait with respect to the backing sheet and fillustrating the same at a larger scale than that shown in Figure 2, and

Figure 9 is a perspective view of similar character *toV that shown inFigure 4 illustrating a slightly modified arrangement of iny invention.

Referring tothedrawings and particularly to Figures 1` tov8 inclusive,my` improved mattress includes a case lowhich is preferably made of therelative sizes as covered in' my above4 mentioned United States patent.For example the case 10. includes end'portions' 11, sides -top v13 and.bottom 14 which are preferably `made of 'flexible cloth; Vthe ends andsides being sewed together and'loeiiigf of Adimensions of thefinishedmattress while the-top 18 andv bottom 14 includes cloth oflarger dimensions than the 4dimensions prescribed by the ends 11' andsides 12.y I form plaits 15 and 16 rin the end and side edgesl of thetop and bottom; the plaits being in line with the rows of tufts.-Directlyadjacent the inner sur faces of the 'top 13 and bottom 14, I:position backing sheets 17 which, in the present embodiment of myinvention as illustrated, consist of sheets of cloth havingv holes oryopenings 18 arranged inthe present instant-venin rows extendinglongitudinally and transversely. vThus there are portions 19 between theopenings 18 which extend longitudinally and other portions 2O betweenthe openings which extend transversely. These backing sheets may besecured to the top and bottom by rows of stitching 21 which extendlongitudinally through the portions 19 and rows 22 of said stitchingwhich extends transversely through the portions 2O of the backingsheets. The outer edges of the sheets 17 are preferably included in theseam 23 which secures the ends and sides to the top and bottom. Thestitching 21 extends substan` tially at ig-ight angles to the plaits 16while the stitching 22 extends Vsubstantially at right angles to theplaits 15. The plaits 15 and 16 may loe arranged to extend over theopenings 18 so that the excess material 24, which is produced by makingthe plaits in the top and bottom which are of larger dimensions than thesides and ends, can be drawninwardly through the openings 18 and tuftedas shown in Figures 1, 2 and 3 ;y

said tufts beingindicated 'at V25.

By thus arranging the backing sheets with respect to the top and bottom,it will be noted that the crossed and rectangular arrangementof theportions 19 and 20 will hold the top and bottom in their tufted posi;

tion With the plaits in their proper forni and alignment; saidlongitudinal and transversely extending portions 19 and 20 also servingto take up strain on the top and bottom in which the strain will beresisted in common planes since the sheets 17 have themportions 19 andA2O in the. same'plane.

Itdwill be noted that the backing sheets thus `ing sheets, itis an easymatter to quickly 20 form the tufts since all of the parts are retainedin'their proper aligned positions to permit the insertion and tying ofthe tufting members 27.

In Figure 9, l have illustrated the form of my 'invention which issubstantially similar to that above described with the exception thatthe backing sheets, such as the backing lsheet 17a as shown, whichareplaced directly adjacent .the top and bottom are only secured to thecase 10 at the seams 23. In all other respects the construction andarrangement of parts would be the same as thatdescribed in connectionwith Figures 1v to 8 inclusive and I have therefore given correspondingparts similar reference characters. Y

Vhile I have describedmy invention as taking a particular form, it willbe understood that the various parts el: my invention may be changedwithout departing from the spirit thereof7 and hence I do not limit'myself to the precise constructionset forth, but'consider that l am atliberty to make such changes and alterations as Jiiairly come within thescope of the appended claims. Y

JHaving thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A mattress including sides and rendsforming a frame having the outer-dimensions oi the' finished mattress; abacking sheet of the length and breadth of the finished mattress withits edges securedto the frame; spaced openings in the backingv sheet,and a cover of greater' dimensions thanvthe finished mattress adapted tobe drawn into the openings inthe backing sheet by the tufting stitches.

2. A mattress includingsides and ends forming a frame having the outerdimensions cf the finished mattress; a backing sheet of the length andbreadth of the iinished mattress with its edges secured to the iframe;spaced openings in the backing sheet7 and @over of greater dimensionsthan the finished mattress, the cover being plaited at the ends Aandsides in line with the tufts and adapted to be drawn into the openingsin the backing sheet by the tufting stitches.

In testimony whereof I have signed my name to this specification 1n thepresence of Vtwo subscribing witnesses.
